Due to social and environmental changes, electronic products are gradually developing towards environmental protection and energy saving. Therefore, in order to achieve the goal of energy saving and carbon reduction, how to improve the efficiency of transformers is really a important current issues.
图1为现有的变压器示意图。如图1所示,变压器1包括一磁芯组10及一绕线11。磁芯组10具有一绕线空间100,绕线11具有一第一出线端111及一第二出线端112,且第一出线端111及第二出线端112分别具有一裸线端B。现有作法将两个变压器1固设于电路板2上,并将第一出线端111的裸线端B以及第二出线端112的裸线端B分别焊接于电路板2上对应的连接点,以使两个变压器1的绕线11互相串联。然而,通过电路板2连接两个变压器的连接方式会导致过多的能量损耗。Figure 1 is a schematic diagram of an existing transformer. As shown in FIG. 1 , the transformer 1 includes a magnetic core set 10 and a winding 11 . The magnetic core set 10 has a winding space 100 , the winding 11 has a first lead end 111 and a second lead end 112 , and the first lead end 111 and the second lead end 112 have a bare wire end B respectively. In the existing method, two transformers 1 are fixed on the circuit board 2, and the bare wire end B of the first outlet 111 and the bare wire end B of the second outlet 112 are soldered to the corresponding connection points on the circuit board 2 respectively. , so that the windings 11 of the two transformers 1 are connected in series. However, the way of connecting the two transformers through the circuit board 2 will cause excessive energy loss.
此外,为符合安规的标准,焊接于电路板2的第一出线端111的裸线端B以及焊接于电路板2的第二出线端112的裸线端B,其与第二级绕组和磁芯组10与电路板2次级元件之间必须间隔一特定距离,例如:8毫米以上,以达到安规要求距离。于此情况下,电路板2空间运用会变差,换言之,通过电路板2连接两个变压器的连接方式会局限空间上的配置,并导致小型化的设计难以实现。In addition, in order to comply with safety standards, the bare wire end B welded to the first outlet end 111 of the circuit board 2 and the bare wire end B welded to the second outlet end 112 of the circuit board 2 are connected to the second-level winding and There must be a specific distance between the magnetic core set 10 and the secondary components of the circuit board 2 , for example, more than 8 mm, so as to meet the distance required by safety regulations.

In other words, the connection method of connecting the two transformers through the circuit board 2 will limit the space configuration and make it difficult to achieve a miniaturized design.
有鉴于此,如何发展一种整合式变压器,以解决现有技术的缺陷,实为相关技术领域者目前迫切需要解决的问题。In view of this, how to develop an integrated transformer to solve the defects of the prior art is an urgent problem to be solved by those in the relevant technical fields.
